I've installed 4 GPU-equipped servers in my environment; 2 are a part of
my cluster, and 2 are independent from the cluster so that users can
login interactively and program/debug/tinker/whatever. (My cluster
doesn't allow interactive logins by design).
A handful of users were interested in getting access to the GPUs, but so
far, not a single one has even logged into these systems to kick the
tires yet, and the systems have been online for approx. 9 months. It
just be that they're busy with other work. Most of my users are
post-docs who guide their own research, so they can create/modify their
own project schedules as they see fit.
